  2. Power over Ethernet - Wikipedia

    en.wikipedia.org/wiki/Power_over_Ethernet

    In this configuration, an Ethernet connection includes Power over Ethernet (PoE) (gray cable looping below), and a PoE splitter provides a separate data cable (gray, looping above) and power cable (black, also looping above) for a wireless access point. The splitter is the silver and black box in the middle between the wiring junction box (left ...

    en.wikipedia.org/wiki/Home_network

    The switch is used to allow devices on the home network to talk to one another via Ethernet; while the needs of most home networks are satisfied with the built-in wireless and/or switching capabilities of their router, some situations require the addition of a separate switch with advanced capabilities. For example the fact a typical home ...

  4. Power over - Wikipedia

    en.wikipedia.org/wiki/Power_over

    Power over may refer to various forms of powering devices over data links: Power over eSATA (eSATAp), a variant of eSATA also delivering power over the same cable (but not the same wires inside the cable) Power over Ethernet (PoE), a method to power devices over their Ethernet cable (shared wires for data and power) Power over fiber (PoF ...

  5. Ethernet physical layer - Wikipedia

    en.wikipedia.org/wiki/Ethernet_physical_layer

    Using point-to-point copper cabling provides the opportunity to deliver electrical power along with the data. This is called power over Ethernet and there are several variations defined in IEEE 802.3 standards. Combining 10BASE-T (or 100BASE-TX) with Mode A allows a hub or a switch to transmit both power and data over only two pairs. This was ...

  6. Network switch - Wikipedia

    en.wikipedia.org/wiki/Network_switch

    A modern switch may implement power over Ethernet (PoE), which avoids the need for attached devices, such as a VoIP phone or wireless access point, to have a separate power supply. Since switches can have redundant power circuits connected to uninterruptible power supplies, the connected device can continue operating even when regular office ...

    en.wikipedia.org/wiki/Fibre_to_the_Office

    The FTTO switch provides a connection between optical uplinks and electrical downlinks. Typically, the switch has up to five twisted pair ports supporting Power over Ethernet (IEEE 802.3af, 15.4W per Port) and Power over Ethernet Plus (IEEE 802.3at, 30W per Port). Modern FTTO Switches offer speeds of 1 Gbit/s per user port (Gigabit Ethernet).

  8. Dell Networking - Wikipedia

    The PowerConnect 5500 series switches are gigabit Ethernet access-switches, available in 4 models: either a 24 or 48 port gigabit Ethernet switch or a 24/48 port gigabit Ethernet switch with Power-over-Ethernet option. Regardless of the model, the switches offer two HDMI ports for stacking and two SFP+ 10Gbit transceiver ports for 10Gb uplinks ...

  9. Registered jack - Wikipedia

    en.wikipedia.org/wiki/Registered_jack

    The micro ribbon connector, first made by Amphenol, that is used in the RJ21 interface, has also been used to connect Ethernet ports in bulk from a switch with 50-pin ports to a Cat-5 rated patch panel, or between two patch panels. A cable with a 50-pin connector on one end can support six fully wired 8P8C connectors or Ethernet ports on a ...
